Magnetic Correction of Materials with Weak Magnetism Signals

Abstract:

For studies of the magnetic characterization of materials with weak magnetism signals, an improved magnetic correction method is proposed to subtract the signal arising from the substrate. The magnetic moment error arising from fitting the data and the system measurement error have been calculated. The influence of nonlinear M-H curves for the substrates has been analyzed and compared with the traditional method of subtracting the substrate signal. Standards determining the presence of ferromagnetism in materials with weak magnetism signals are suggested. The improved magnetic correction method provides a criterion for clarifying confusion in the characterization of materials with weak magnetism signals.
